What data the app uses

Exactly which Shopify data a subscription app needs, what it never touches, and how deletion works.

A subscription app necessarily touches customer data. Here is exactly what, and what it never does.

Data	Why the app needs it
Subscription contracts	The subscriptions themselves: products, prices, schedule, status.
Customer name, email and phone	To show the subscriber on their subscription, let them into their own portal, and send recovery and lifecycle emails.
Order data	To show real per-delivery status in the portal timeline and link each delivery to its order.
Payment method status	To tell whether a failed charge is a card problem, so the right recovery goes out. Never the card details themselves.
Products and variants	To attach offers and show what is on a subscription.
Theme and files	To detect where the widget sits and resolve your logo for the portal.

What the app never does

It never stores card or bank details. Payment data stays with Shopify and its payment providers. A card update is done on Shopify's own secure page, reached by a link Shopify emails the buyer.
It never sells or shares customer data.
It never sends customer data to an AI model as a way of identifying anyone. Retention features work from behavior on the store: cycles delivered, cycle value, cancel reasons, risk factors.

Deletion

The app implements Shopify's mandatory privacy webhooks: a customer data request, a customer redaction and a shop redaction. Uninstalling the app closes out the store's data on the schedule set out in the privacy policy.
